spotlight | nullPlayers can control the character with the arrow keys | Keyboard library

I'm having trouble running some C code before launching an app from Spotlight or the Applications folder. I figured I should just be able to create an executable with my code where after all the computations are done I make a execvp() call to run the original app's executable, which will then replace the current process.

I compiled the .c file and gave it the original app's executable name (in my case clion) and then executed it from Terminal.. great, it works!.. Until I tried to open the app bundle from spotlight (or Finder)

For some reason the execvp() call fails and the original program continues, but my custom executable is indeed called by spotlight! Not even making a child process with fork() will work, neither a system() call. What could be the problem here?

Contents folder of CLion: clion is my executable, clion-real is the original executable

I have written a python program that needs a first command line argument to run from the Terminal. The program can be used to copy a text to the clipboard when it is run with a certain keyword.

I'm building a newspaper add (kinda) with two lists views: one list view contains 4 articles from 2020 and the other one has 4 articles from 2021. When the user clicks on an article title, webview opens up the article.

However, I've only previously used one list view and one onItemClick method. I'm really not sure how to get onItemClick to access two different list views when both lists have items in position 0,1,2,3.

With the current code I have each time a user clicks for example on the first link, it will open the article of 2021 of case 0 and then the article of 2020 of case 0.

This is the XML code:

I had a working 3d model viewer in react, which i am now trying to port to Next. I need GLTFLoader and OrbitControls which are giving me the problem in react I loaded this like:

I have a functional react component and initial load a gltf model - the path gets passed through the props - this works fine.

But if the props change the component rerenders - I checked that - the path is changed and a new Model should be loaded - but I does not.

How can one achieve this? I want to swap/replace the object that is rendering if the state is updated.

I tried different loaders, set the gltf it self as a state but none of this wokred. I think I miss an underlying concept. Pls Help

all.

I'm working with three.js 127, following the documentation to add a SpotLight. However, shadows won't get shown on the scene. Below, you can find my scene. I already set the plane to receive shadow as well as other elements enabled to cast shadows yet no shadows are rendered on the scene.

I'm building a page with two overlapping components and i want to pass mouse events from the top component to the bottom one.

I'm using ReactJs and the code looks like this:
